Hi All,

I cant seem to get the I2C Module to interrupt my processor.
I setup th IIC1F register for 100kbps,
I put #%11111000 into the IIC1C register,
I clear the IIC1S register and then,
I put the address of the slave into the IIC1D register and RTS

I was under the assumption that I should now get an interrupt from the I2C module when the transfer is complete, but this is not happening Crying or Very sad

Anyone?

Hi,

Look at sei/cli, any other interrupt mask bits, do SW simulation first, check all the interupt mask chain and so on... Or send more info or code sample.

Thanks for the reply.
Problem solved, I was not sending a start signal. Supposed to toggle Master Mode Select Bit in the IIC1C register from 0-slave mode to 1-master mode in order to send a start signal.

Didnt read the book properly.....
Live and learn I suppose.....
